Synchronization and bistability of qubit coupled to a driven dissipative oscillator
O. V. Zhirov, D. L. Shepelyansky
We study numerically the behavior of qubit coupled to a quantum dissipative driven oscillator (resonator). Above a critical coupling strength the qubit rotations become synchronize…
Synchnonization, zero-resistance states and rotating Wigner crystal
A. D. Chepelianskii, A. S. Pikovsky, D. L. Shepelyansky
We show that rotational angles of electrons moving in two dimensions (2D) in a perpendicular magnetic field can be synchronized by an external microwave field which frequency is cl…
Photogalvanic current in artificial asymmetric nanostructures
A. D. Chepelianskii, M. V. Entin, L. I. Magarill +1
We develop a theoretic description of the photogalvanic current induced by a high frequency radiation in asymmetric nanostructures and show that it describes well the results of nu…
Quantum error correction of coherent errors by randomization
O. Kern, G. Alber, D. L. Shepelyansky
A general error correction method is presented which is capable of correcting coherent errors originating from static residual inter-qubit couplings in a quantum computer. It is ba…
Directing transport by polarized radiation in presence of chaos and dissipation
A. D. Chepelianskii, D. L. Shepelyansky
We study numerically the dynamics of particles on the Galton board of semi-disk scatters in presence of monochromatic radiation and dissipation. It is shown that under certain cond…
Statistical properties of eigenvalues for an operating quantum computer with static imperfections
G. Benenti, G. Casati, S. Montangero +1
We investigate the transition to quantum chaos, induced by static imperfections, for an operating quantum computer that simulates efficiently a dynamical quantum system, the sawtoo…
